A recent CIO editorial by Bernard Golden regarding the future of private cloud spurred some interesting commentary in my network. The pushback seemed to focus around the viability of the term “private cloud”. These individuals are well-respected thought-leaders in cloud with significant experience guiding senior IT executives transition to modern architectures, so I decided I’d engage them in a discussion regarding the future of self-managed infrastructure as a whole.

There’s a class of individuals, myself included, whose job it is to advise and recommend direction in Enterprise IT. In this role, we live in a bubble of sorts. I believe most of us understand the realities of Enterprise IT very well, but we also have a good handle on next generation architectures, their value, and how to migrate current IT environments to these next generation architectures. We understand the constraints of public cloud environments as well as other as-a-Service offerings. However, being outside of the day-to-day operational demands of the business, it’s easy for us to “see the light” more easily than someone who is confronted daily with typical Enterprise IT demands.

This bubble also means that we need to check ourselves from time to time against reality and question what we consider to be the optimal solution for businesses. For me, this meant engaging what I consider to be some of the most intelligent and knowledgeable individuals on cloud computing and Enterprise IT. Individuals who also meet with key senior executives in IT on a daily basis to discuss their goals to engage in discussions about balancing the vision and reality.

What ensued was a lively discussion that uncovered realities to balance the hype for businesses migrating to the cloud.

The initial ask was to provide two pro and two cons for businesses to continue investing in their own managed infrastructure (data centers or co-location). As the conversion ramped up this group was also requested to provide their insights in businesses moving “whole hog” to the public cloud.

I’ll summarize the responses to the initial request first.

With regard to support for businesses needing to continue to manage and continue investing in their own infrastructure:

Data Gravity (scale of data to voluminous to easily migrate the apps and data to the cloud)

Security

Emerging scalable solutions (e.g. Hyperconverged)

Lack of equivalent SaaS offerings

Significant integration requirements

Lack of ability to support migration to cloud

Vendor licensing

Network latency

Transparency

Avoid Lock-In

With regard to support for business exiting infrastructure/data center management activities:

Operational costs

Availability of skilled workforce

Better capital management

Difficulty in providing elastic scalability

Agility

Perception of being considered pro-data center

Limiting innovation

Poor imitation of public cloud experience

Poor capacity management / resource utilization

Avoid extremism

Interesting, huh? Across a large enough population of really talented and experienced individuals emerged ten reasons for each position. You can argue the viability of certain ones, but all-in-all it’s an interesting outcome given the hype about companies moving to public cloud and CIOs all claiming they’re looking to exit the data center business.

I reiterate one of Tim’s messages, “IT is complex!”. We should know by now that there’s no silver bullet solutions, but attempts to buy them have ended in failure time and time again. And, yes, the message that the future world will be a hybrid one is starting to become more prevalent. Yet, there’s still a growing perception that self-managed data centers/infrastructure is a bad thing and businesses should have a strategy for exiting their current investments. Of note, the answer doesn’t have to be “public cloud”, a reasonable solution is to offload this to a managed services provider.

Notables

If you’re looking to learn from the best, here’s a set of quotes taken from the discussion thread. It’s an incredible resource chock full of knowledge and experience from some of the world’s most knowledgeable IT experts.

Sadly, I’ve run across two business leaders recently who believe that the cloud is fragile and concerned about security and the grid going down (yikes!).”

I’m not of the camp that believes all roads lead to Public Cloud. It is one of many tools that an organization can leverage in their arsenal. If we do move everything to these three (from the myriad of existing data centers…or internal providers), we will in-fact be building a house of cards. A perfect target for malicious and disruptive activities too

I suspect we’re picking on some philosophical differences in our believe of where things end. If you believe that all roads end with Public Cloud, you will have one perspective. If you believe in a more complicated (and I hazard to use the word hybrid) reality, then you will have a different response. There is both an opportunity component and a time component.

I’ve heard:

Come hell or high water (heard it’s a great movie) we’re just going to move everything regardless of what it takes

We’re going to keep primary applications in house and secondary ones in public cloud

We’re going to use a retirement approach as apps are grandfathered out their replacement is “cloud first”.

Little to no public cloud

All on AWS

, etc.. I’ve heard each of the above from good sources, along with the indication that this wasn’t a one-off sentiment.

There has never been a good “monopoly”

Moving “all” to public cloud is a tough nut to swallow for most. There are a significant number of hurdles that the average IT organization must overcome before they can safely and successfully make that kind of move; Is there a well-defined value to making an immediate move? Do we have the internal resources to accomplish the move while not significantly disrupting on-going operations and development? Can we justify having all our eggs in one basket? If we don’t put all our eggs in an AWS or Azure basket, how do we safely, securely and efficiency manage a multi-cloud portfolio?

There are modern organizations that have already spent over three years in attempting their move of “all” to a specific cloud provider and they aren’t done. Where there is less understanding among customers is what their future looks like when they no longer own any of these traditional infrastructure based services. Will they be beholden in a bad way to a less than benevolent dictator? Will changes in service quality affect their ability to effectively support their customers? Can they have confidence in their ability to manage costs? In other words, “we’ve moved the brain out of the body, do we really know everything we need to know about how that will work long term?”

I expect that the long term is higher order abstractions that run 90/10 on public/private systems and are relatively standardized such that businesses can focus on where business value is in their IT supply chain. Meanwhile, some folks will always need to go their own way because they are pushing the envelope (Hi DropBox).

In regards to ability to deal with scale IE keep it staffed, the hyper scale guys will suck up all the talent, think data gravity but more like “skills gravity”. Can they handle the scale IE number of machines/facilities, these guys are good at what they do because of awesome amounts of focus on the supply chain

I’ll put this out there……. Who wants to be the CIO who signs off the next PO for a new DC?? Isn’t this just career suicide?

Here’s my issue with modern DC & enterprise-focused software today. Excluding Salesforce and Amazon, most of the major enterprise players today built their software and systems 25+ years ago in an age where security was an afterthought (at best), the internet didn’t exist within the context DC operations and the majority of employees didn’t have or need access to company resources 24/7.

For mission-critical systems that are built on “iterated upon” architectures and technologies – and require extreme integrations with existing internal and external systems, investing in modernizing or adding HA/DR capabilities (yes, I’m looking at you Aviation & Retail Banking) is also (IMHO) a perfectly valid reason to spend $$. In many cases and many industries, there are simply no SaaS solutions to purchase, and moving to public cloud IaaS could arguably make systems even more complex to operate. The risks are simply not worth it.

Think about all the compute power across just the Fortune 500. Now take all of that and dump it on Amazon, Microsoft & Google. Are we expecting too much from them? Will they be able to handle this? Can they staff enough people to run data centers large enough to continually deliver elastic resources to this audience?

You have to hire high-skilled IT talent in a low-value activity and are prevented from spending that money on talent in other areas that could improve your business outcomes, e.g., application developers

Most CIO’s (I know) are pragmatists, while they have a view on the “horizon” they are tactically mixing and matching their DC strategy “service by service”.

Like any real estate, it’s location, location, location for datacentres. Think of them like gated communities; you want to have great neighbours you can interconnect with, not ones you want nothing to do with, nor an industrial estate with a small number of large wholesale footprints, and certainly not an empty estate. You should look for carrier-neutral facilities with plenty of telcos, as well as internet, cloud, financial, and other exchanges.

You can hug your servers. Regulators like that, but change is the stroke of a pen away (and coming soon to a jurisdiction near you). Gartner reckon “no cloud” policies will be gone within a few years.

Summary

I have to admit I was completely surprised by the level of participation in this thread. This particular group is very busy with their daily business activities and was thoroughly pleased with what we were able to create. I am grateful they took the time to add their knowledge and experience to this query. Their Twitter handles are all listed above and I highly recommend you follow.

At a time when the media presents sensationalistic views that skew reality, it’s critical to stop and assess what is being presented. Unicorns are great, but they’re mythological beasts. Can you learn from them? Sure. Can you be them? Perhaps a better question is, “should you be them?” The following sums this up best in response to releasing the draft of this entry for review:

“What we’ve done here really demonstrate the “It’s complicated” statement, which is the truth of the matter. The “Netflix poster child” for cloud adoption is not representative of most others cloud journey. The low hanging fruit are on the cloud, now the real work begins. (not to undermine the great work the early adopters did)”
